Description
Castrol Alpha SP 680
Product Description
Castrol Alpha SP 680 is a premium mineral-based extreme pressure (EP) industrial gear oil formulated with highly refined base oils and advanced EP additive technology. It is designed to provide excellent load-carrying capability, wear protection, thermal stability, and micropitting resistance for heavily loaded industrial gear systems. The formulation helps extend gear life and meets the demands of modern high-output gearboxes.
Key Features & Benefits
- Excellent extreme pressure (EP) performance
- High load-carrying capacity under severe operating conditions
- Advanced micropitting protection for extended gear life
- Good thermal and oxidation stability
- Excellent wear and corrosion protection
- Good water separation and demulsibility characteristics
- Low deposit formation ("clean gear" technology)
- Compatible with common seal materials used in industrial gear units.
Typical Applications
- Enclosed industrial gearboxes
- Spur and helical gears
- Splash, oil bath, and circulation lubrication systems
- Heavy-duty industrial transmissions
- Mining and cement industry equipment
- Marine gearboxes, thrusters, and deck machinery
- Some lightly loaded worm gear applications.
